Saw this project when I was looking for a software/hardware combo that would allow me to plug an Apple ][ Grappler Card into it and emulate a parallel port printer: http://www.retroprinter.com
Seems like the project is dead/stalled. I wonder how hard it would be to do something similar with the RS422 port on my Mac 512k to allow me to print to a modern laser printer.

The Grappler 9-pin and LX/LQ series sold for Macs itself was a hardware printer emulator (it will convert ImageWriter ESC codes to Epson FX ESC/P codes).
Honestly, its easier to use serial as the RPi just needs a commonly available USB-to-serial adapter to interface with the vintage machine (all Macs have serial and the Apple II Super Serial card is easy to find). On the software end, GSport has a ImageWriter LQ emulator built into it. Its fairly modular, all it really needs is to be written as a daemon to monitor the serial port for data to process and forward to CUPS on the Linux end.
